Generally, we ask that you cite our collections in the following manner:
[Name of collection], Drexel University Archives
For example, please cite a letter in the MacAlister collection this way: "James MacAlister papers, 1889-1941, Drexel University Archives."
Students, if you are citing a collection for an assignment, be sure to ask your instructor which style manual s/he prefers! Check out the library's citation style resources
for more help with citations.
